By the way, you can find out the dealer cost at
http://www.carcostcanada.com - I think you have to pay $40cdn to find out the cost of 5 different vehicles but it's definitely worth it. Side-by-side, you can see the MSRP and dealer cost along with current rebates, incentives, and financing options.
Keep in mind that the listed cost might not be what your dealer paid - they get discounts for buying large quantities, etc.
Some dealerships offer you a price directly through the site, but they're not the best offers - a local dealership automatically offered me $1000 above cost, but I one-upped them with getting it at cost. (yeah me)
As a general rule of thumb, Nissan's and Honda's aren't marked up that much in Canada. Expect a max of 9% below MSRP for domestic vehicles and 7% off MSRP for imports - at least, that's what I heard.
